A modest recall has been issued by Mercedes-Benz for approximately 300 units of the EQB, the electric variant of the GLB. Constructed in 2022, the crossovers that were part of the promotion had a defective weld in the electric motor of the front axle, which may cause them to roll away while parked.

The National Highway Traffic Safety Administration (NHTSA) has designated recall number 24V-331 for a total of 283 vehicles, comprising 183 2022 EQB 300 units and 100 2022 EQB 350 examples. The gasoline-powered GLB and front-wheel drive EQBs are not covered by the recall. The crossovers in question were manufactured between February 18, 2022, and January 23, 2023, according to Mercedes-Benz.

The problem was identified by the manufacturer as a welded spur gear in the front axle motor. “The weld might fail,” according to it, which “would allow the differential spur gear to rotate freely from the differential assembly within the front axle electric drivetrain.” In that case, even if the driver chooses Park, the pawl on the mechanism won’t stop the EQB from rolling away. However, you may stop the crossover from rolling off by applying the electronic parking brake, which activates automatically when the EQB is turned off or the driver’s door is unlocked.

Mercedes-Benz warns that the weld may break suddenly. When it breaks down, there may be loud rattling sounds made while driving.

When Mercedes-Benz got field reports identifying this issue from sources outside of the American market in June 2022, engineers started investigating. It states that the weld breaks on the spur gear “because of excessive material hardness.” It states that even if the front motor has a problem, the rear-mounted motor will still function according to its design, allowing the EQB to continue operating. Although the company has received five warranty claims, field reports, and service reports, it is not aware of any incidents involving accidents, injuries, or fatalities.

The solution is quite simple. Owners of the 100% of recalled EQBs will need to contact a Mercedes-Benz approved dealership in order for a technician to replace the motor in the front axle. Prior to July 9, 2024, the business intends to mail notices to owners.
